Apparently there is a fanmade visual novel for Conclave (I found about it through the development tumblr here). It's called Delectatio Morosa. [Info]

...I... kind of want to play it?

This movie sank its claws into me in the weirdest way and now I want more. I don't know how this happened.

I have read the book and now I kind of want to rewatch the movie, though admittedly that is partially because I want to thirst after Carlos Diehz. I don't know what it is exactly but he is absolutely magnetic as Vincent Benitez.

....Maybe I will play the game too. If I can find time.
